Hope you’re good and that’s a great question.
The very nature of Snapchat means that it creates temporary moments of content, which translates into a more engaging and intimate experience for the user. The use of temporary content posted/sent by someone/brand that you care about means that the users willingness to engage is increased, which is why Snapchat deserves some attention.
The challenge for event organisers with Snapchat is making sure that they create relevant content for that platform. Unfortunately, the same video/poster that you share on Facebook may not be suitable for Snapchat because the rules of engagement are very different (by design).
Hopefully this blog we did will give you some insights into what works - http://snappylookers.com/2017/08/03/when-tradition-tries-new-media/
All in all, Snapchat is a great platform to market events, but it’s worthwhile thinking about your target audience and the right content for them before taking the leap.
Hope this helps,
